The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

CASSONDRA LUX-O'CALLAGHAN, OD appears in the CMS NPPES registry as a Optometrist provider holding OD credentials at 711 N CUSTER AVE STE G, GRAND ISLAND, NE, 68803, with a listed phone of (308) 865-2760. NPI 1386121911 was issued on 07/26/2018.

Medicare Part D records for calendar year 2023 show 564 prescription claims written by this provider, covering 169 Medicare beneficiaries and totaling roughly $90K in drug spend, split 50% brand-name and 50% generic by claim count.

Optometrist is a high-volume specialty nationwide, with 60,463 enrolled providers across 56 states and an average of 257 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
